TEMPORARY BINDER.

Specification of Letters Patent.

Patented.- May 21, 1907.

Application filed April14, 1906. Serial Nn. 311,777.

To all whom it *may concern.-

Be it known that I, CLYDE J. BRYANT, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Tem orary Binders, of which the following is a full, clear, and exact description, reference being had to the accoinanying drawing, forming part of this specication.

My invention relates to that class of temorary binders in which the sheet holding evioes are equipped with arch-shaped prongs adapted to receive perforated sheets of paper to detachably hold'them in the binder and the invention has for its object to provide a simple and eflicient construction whereby the prong carrying members are rocked to and fro to bring the free ends of the prongs into abutting positions to confine the sheets of paper and to separate said free ends for the removal of the sheets.

Figure I is a perspective view of my binder. Fig. II is a top or plan view of the portion of the binder at which the prong carrying rod actuating means is located. Fig. III is a longitudinal section taken in art on a line through the central portion of the back of the binder and in part through one of the prong carrying rods and showing the rod. actuating member in elevation. Fig. IV is a cross section taken on line IV IV, Fig. II. Fig. V is a similar view to Fig. IV, with the sheet receiving prong shown in open condition and the cover of the binder omitted. Fig. VI is a perspective view of the end of one of the prong carrying rods that receives the rod actuating means. Fig. VII is a perspective view of one ofthe rod receiving pocket members. Fig. VIII is a perspective view of the reciprocatory memher by which the sheet carrying rods are actuated. Fig. IX is a similar view to Fig. V illustrating a modification of the pocket members.

A designates the cover boards of my binder which are flexibly united to a back cover section B. These parts may be of any ordinary construction and no invention per se is herein claimed for them.

1 designates a back strip which is secured to the back cover section B in any suitable manner and which may be of any suitable stiif material, such for instance as wood or paper board.

2 designates a pocket member secured to the back of the binder at one of its ends and having pockets extending longitudinally thereof.

3 designates a pair of rockable rods having ends thereof loosely seated in the pockets of the pocket member 2 so that they may turn therein. The rods 3 are preferably tubular and each rod is provided with a plurality of sheet receiving prongs 4 of any desirable number that are adapted to have their free ends brought together in mating pairs when the rods are rotated in one direction, or their free ends separated when the rods are rocked in the opposite direction. In each rod 3 at its end opposite that which is seated in the pocket member 2 is a cam shaped slot 5 ex tending longitudinally of the rod and of such configuration that when a part to be hereinafter referred to is moved in said slot the rod to which it applies will be rotated to a desired degree to cause the prongs 4 which receive perforated sheets of paper to be thrown apart or to be moved in the opposite direction to bring their free ends into abutment with each other.

6 designates a pocket member secured to the back of the binder at the end of said back opposite that at which the pocket member 2 is applied and by which the ends of the prong carrying rods 3 that contain the cam slots are received. The pocket member 6 is constructed of a single piece of sheet metal and it consists of a flat portion that rests against the back of the binder and a pair of approximately cylindrical pockets 7 which are produced by bending the plate of metal at its sides into tubular form. The pockets 7 are formed of a size that will cause the prong carrying rods 3'to fit snugly therein but with sufficient looseness in order that they may be readily rotated. Each pocket of the pocket member 6 is preferably provided with a longitudinal slot 8. The pocket member 6 is secured to the back of the binder by prongs 9 which are struck from the plate of said member and are adapted to be passed through the stiffener strip 1 of the binder back and then bent over onto said stiffener, thereby securely attaching the pocket member to the cover of the binder without any other means of fastening. A very simple and strong attachment of the pocket member to the cover is by this means provided due to the prongs being integral with the pocket member which they serve to hold from displacement. The pocket member 2 is preferably secured to the cover of the binder in the same manner as that described relative to the pocket member 6.

10 designates a pair of slide rods arranged to operate in the ends of the prong carrying rods 3 that are seated in the pockets 7 of the pocket member 6. These slide rods extend beyond the ends of the prong carrying rods in which they are seated and they are connected by a finger piece 11 of such shape that it may be readily grasped to reciprocate the slide rods in the prong carrying rods. Each slide rod 10 has extending laterally therefrom a stud 12 that is adapted to operate in the cam shaped slot 5 of the prong carrying rod in which said slide rod is fitted, in order that when the slide rods are moved in one direction, for instance outwardly, said studs will be operating in the cam shaped slots of the rods to impart rotation to the prong carrying rods to separate the free ends of the sheet receiving prongs from each other, whereas when the slide rods are moved in the opposite direction said studs will operate in said slots to rotate the prong carrying rods and move their free ends into abutment with each other in mating pairs. It is obvious that the cam shaped slots 5 in the prong carrying rods extend in said rods in directions diverse from each other in order that the studs of the slide rods operating in said slots will act to impart rotation to the prong carrying rods in opposite directions for the purpose of causing the sheet receiving prongs to be thrown toward or away from each other. The studs of the slide rods preferably extend through the longitudinal slots 8 in the pockets of the pocket members 6 to operate therein when the slide rods are reciprocated.

I wish to call special attention to the fact that the sheet receiving prongs of my binder are rigidly carried by the rockable rods 3 and are therefore always maintained in fixed po sitions instead of being susceptible of wabbling motion, such as that present in the mounting of sheet receiving prongs in temporary binders in which the prongs are loosely mounted upon fixed pivots, and which therefore have unsteady motion when moved in opening and closing them and which are also unsteady when papers are confined thereby.

In the modification illustrated in Fig. IX, I have shown a pocket member 6 in which the pockets that receive the rockable rods 3 are produced by bending the plate from which the pocket member is made upwardly, downwardly and outwardly into substan tially tubular form instead of bending the plate in the manner previously explained. In this construction the pocket member 6 has its downwardly extending edges pro vided with a plurality of spurs or prongs 9 arranged parallel with each other and adapted to be passed through the stiflener strip of the back of the binder and then bent laterally to secure said pocket member to the binder cover.

I claim:

1. I11 a temporary binder, the combination of a pair of rockable rods provided with sheet receiving prongs, and a pair of connected slidable rod actuating members loosely fitted to said rods and having engagement therewith whereby said rods are rotated in unison, substantially as set forth.

2. In a temporary binder, the combination of a pair of rockable rods provided with sheet receiving prongs, and a pair of connected slidable rod actuating members loosely fitted to said rods and having slot and pin engagement therewith whereby said rods are rotated in unison, substantially as set forth.

3. In a temporary binder, the combination of a pair of pocket members, a pair of rockable rods loosely seated in said pocket members and provided with sheet receiving prongs, and actuating means slidably fitted to said rods and having engagement therewith whereby said rods are rotated in unison when said actuating means is moved in a direction longitudinally of said rods, substantially as set forth.

4. In a temporary binder, the combination of a pair of pocket members, a pair of rockable rods loosely seated in said pocket members and provided with sheet receiving prongs, a pair of slidable rod actuating members loosely fitted to said rods and having engagement therewith to impart rotation thereto said rod actuating members being united to each other, substantially as set forth.

5. In a temporary binder, the combination of a pair of pocket members, a pair of rockable rods loosely seated in said pocket members and provided with sheet receiving prongs, a pair of slidable rod actuating members loosely fitted to said rods and having engagement therewith to imp art rotation thereto, and a finger-piece connecting said rod actuating members, substantially as set forth.

6. In a temporary binder, the combination of a pair of pocket members, a pair of prong carrying rods loosely seated in said pocket members and provided with cam slots, and a pair of slidable rod actuating members loosely fitted to said rods and having portions thereof arranged to operate in said slots, substantially as set forth.

7. In a temporary binder, the combination of a pair of pocket members, a pair of prong carrying rods loosely seated in said pocket members and provided with cam shaped of a pair of pocket members, a pair of prong carrying rods loosely seated in the pocket members and provided With cam shaped slots, a pair of slide rods loosely fitted to said prong carrying rods and having studs ar- 10 ranged to operate in the slots in said rods, and a finger-piece connecting said slide rods, substantially as set forth.
